Actress and campaigner Alyssa Milano has weighed in on a viral video that appeared to show Make America Great Again-hatted high school boys chanting in the face of a Native American veteran near the Lincoln Memorial in Washington, D.C.

“The red MAGA hat is the new white hood," Milano tweeted Sunday, appearing to compare the Trump campaign merchandise to robes worn by the Ku Klux Klan. "Without white boys being able to empathize with other people, humanity will continue to destroy itself.”

The tweet was one of several posted by the actress apparently in reference to hotly debated viral footage of the group of boys from Covington Catholic High School in Kentucky. The students were in the capital for an anti-abortion "March for Life" rally, while the Native American campaigner pictured in the video›—Nathan Phillips—was taking part in the Indigenous Peoples' March.

Although the students’ behavior was initially condemned on social and mainstream media, by the boys' school and by lawmaker Deb Haaland, responses to the confrontation shifted as more videos quickly emerged.
